little info in why i decided to sign up:
in the final year of my college course in ireland, control & automation engineering, in DIT.
for our last semester we have to do a 12 week project.
we got a club car chassis with the bare essentials.
we are applying control & automation theory to control this buggy.

i will be in charge of controlling the buggy using a new fx3u mitsubishi plc
also building an independant speed sensor

other projects im overseeing related to this are:
automated steering
dead man sensor
scada datalogging system
control of drive through a PC.

the timeline on these parts are about 6 weeks to implement other stuff afterwards

should be meeting the club car international boss next week as he is interested in our projects and might fly over to meet us face to face :)

we have a 99 regen car with a 1510 curtis cont.

also supplied was a club car motor, not a lot of info apart from seperatly excited dc motor, 48V 3.2 Horsepower mech.

anyone with info on the controller & motor some schmatics would be awesome and very much appreciated. also, we powered up the system using 4 X 12V car batteries, all in pwo.
followed the voltage was getting 48V at every point apart from the negative terminal of the controller.

im guessing that its shot? any tips on telling if it is or if there is something to be done inside the controller?

im getting 48V into the controller, just not out of the controller....

scottyb, surely there would be 48V at the negative terminal of the controller regardless of the throttle input? dont know for sure but i thought the throttle would only vary the field current to the motor?

thanks carryone, had horrible trouble trying to get the info off curtis themselves.

if anyone has any datasheets or schematics for the club car motor that would be well appreciated, as there is not a lot of info on the web i can see.... o.O

graham, i'm looking forward to following your project in the weeks to come! i've been interested in doing some of the same sort of things to my cart. not so much for science and research, but more for my own personal amusement. it'll be interesting to see how you tackle interfacing the steering, especially if you are planning to keep the vehicle drivable by normal means. i have a few ideas, but haven't made any attempts as of yet.

heres a high-res wiring diagram of a regen. not sure if its the same as your make/model so it may not be 100% applicable. cheers!

servo motor geared up onto the steering shaft, either pulsed width modulation through a PIC or the FX PLC.
shouldn't be too hard, have brilliant electrical/electronic/mechanical lectures floating around campus if we get stuck.

will be making a seperate thread to document the progress.

also if anyone out there has info on the club car motor can you please post pics/links?

thanks again peeps

werd! looking forward to it!

diagram on the right (sepex) should be correct unless its a shunt wound motor (im not sure as i don't own a sepex cart). terminals closest to the transaxle are the field, terminals closest to the end of the can go to the armature/brushes. motor sensor should be of the hall effect type, providing 4 pulses per revolution. iirc, the curtis website had some white papers on their sepex controllers, but required some serious digging to locate. cheers!

attached is the Illustrated Parts list for 1999 club car ds models. (16mb) it should shed some insight. since you have gained the interest of club car execs, you could possibly hit them up for a service manual. if they won't give you one, it may well be worth the $80 or so to pick one up. it will undoubtedly save you a lot of time and frustration on research.
